Question

Accepted Answer

Reynolds number is a dimensionless quantity used in fluid mechanics to predict flow patterns. Bernoulli's theorem relates pressure, velocity, and elevation in fluid flow. Columns and struts are structural elements used to support loads. Thermodynamics cycle refers to the process of energy transfer in a system. Journal bearing design involves the selection of materials and lubrication for bearings.

Reynolds number is used to determine whether flow is laminar or turbulent. It is calculated as the ratio of inertial forces to viscous forces.
Bernoulli's theorem states that in a steady flow of an incompressible fluid, the sum of pressure, kinetic energy, and potential energy per unit volume remains constant.
Columns are vertical structural elements that support compressive loads, while struts are inclined structural elements that support both compressive and tensile loads.
Thermodynamics cycle involves processes such as compression, heating, expansion, and cooling to transfer energy in a closed system.
Journal bearing design considers factors such as load capacity, speed, lubrication, and material selection to ensure proper functioning and longevity.
